P10-07 m-Health apps and health-promoting behavior: medical students' opinion

Abstract Background The recent COVID-19 pandemic showed us that the use of digital health technologies could contribute and make health systems and services more effective. People worldwide use digital health solutions to protect their health and promote well-being. WHO recognizes digital health as key to realizing better access to health for people and an important part of the future of health. The aim of the survey is to study medical students attitude towards m-Health applications installed on their devices, assess their usage, and identify their relation to students sport habits. The research as well focused on medical students intention to apply m-Health apps into their clinical practice in order to improve the quality of services provided to patients. Methods In order to achieve the purpose of the study, an anonymous web based questionnaire was used among first year medical students in Medical University -Sofia in Bulgaria, and all the students participated voluntarily. Both the attitudes of the students towards m-Health application, and how sports habits are related with them were measured with closed questions. The study was conducted during January and February 2021. We used a descriptive statistical method to analyze the data. Results Completed questionnaires were received from 133 students. Although the majority of the students (67%) have a positive attitude towards m-Health applications, only half of them (47%) believe that m-Health applications have affected (better and much better) their health-promoting behavior. Data about the use of m-Health applications into their future clinical practice shows that medical students will recommend these applications to their patients (60%), but less than half of them (39%) feel confident with the protection of their patients' personal data. Conclusions The study was conducted to explore medical students' opinion about m-Health applications and the related health-promoting behavior. The results shows that although they are keen in using, and recommending m-Health applications, they still do not trust the treatment of the personal data. It is thus recommended that more efforts should be in the direction of m-Health applications trustworthiness development. Great acknowledge, and guidelines in this area are important to ensure the wider use of m-Health applications.


Background
Older adults often fail to reach the recommended amount of physical activity to prevent the age-related decline in metabolic, cardiorespiratory, and muscular function. Effective home-based physical training programs could neutralize barriers preventing older adults from being active, and administration/supervision through videoconference may be an optimal solution. The present randomized controlled trial aimed to test the non-inferiority of training program administered through videoconference against the same program administered face-to-face in healthy older adults. Methods Participants were randomized in a no-training control group (n = 13), a face-to-face training group (n = 15), and a videoconference training group (n = 13). The intervention groups completed the same home-based, structured, progressive and combined training program for 16 weeks, 1-hour twice a week. Pre-intervention and post-intervention evaluations included body composition, cardiorespiratory fitness and muscle function measures. The non-inferiority margin was calculated by comparing the face-to-face training group to the no-training control group.

Results
Non-inferiority of videoconferencing against face-to-face training was observed for changes in body weight (p>.01), fat mass (p=.015), maximal aerobic power (p=.013), maximal heart rate (p=.034), maximal oxygen consumption (p>.01), knee extension strength (p=.044) and lower limb power (p=.019), but not for muscle mass (p=.067), handgrip strength (p=.171), trunk extension strength (p=.241) and knee flexion strength (p=.462). Conclusion A training program administered through videoconferencing was not inferior to the same program administered face-toface for reducing body weight and fat mass, and for improving maximal aerobic power and oxygen consumption as well as lower limb power and knee extension strength in healthy elderly subjects. However, videoconferencing training was not as effective as face-to-face training for improving handgrip, trunk extension and knee flexion isometric strength, possibly Abstract citation ID: ckac095.146 P10-07 m-Health apps and health-promoting behavior: medical students' opinion

Social media could have an impact in this effort because of its enormous reach, potentially addressing underserved populations in need for PA interventions. To date, characteristics and effectiveness of social media-based interventions for the promotion of PA are not well understood. This scoping review provides a broad overview of existing social media-based interventions and systematically maps the evidence regarding their effectiveness for PA promotion and other health outcomes. Methods Scopus and Medline were searched for the terms 'physical activity', 'social media' and key social media platforms. Following the PRISMA guidelines for scoping reviews (PRISMA-ScR), two reviewers independently screened abstracts and full texts for eligibility. Any discrepancies were resolved by a third reviewer.
